Question

The monthly income of A and B are in the ratio 5:4 and their monthly expenditure are in the ratio 7:5. If each saves rupees 9000 per month, find the monthly income of each​

Answer 1

Answer:

30000 & 24000

Step-by-step explanation:

as you can save money by cutting down your expenses so assume A asd B  expenditure is 7x and 5x

hence, 7x-9000/5x-9000=5/4

                      4*(7x-9000)=5*(5x-9000)

                      28x-36000=25x-45000

                      by solving ,  x=3000

expense of A is 7x=21000 and B is 5x=15000

and when we add their savings it becomes 30000 and 24000 , which satisfy income ratio 4:5
